As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Connects AtlasTexture to its `atlas`'s "changed" signal, allowing it to detect property changes to `atlas` and update accordingly, when the project is running and in the editor, as well.
`fps` has been turned into `speed_scale`. It now affects the scale of the entire animation. If `speed_scale` is a negative value, the animation is played in reverse.
`frame_n/delay_sec` has been renamed to `frame_n/duration` _(prefixes exist, making the previous name redundant)_.
Setters and getters, documentation updated, too.
* Replace case-by-case extraction with PNAME & GNAME
* Fix group handling when group hint begins with property name
* Exclude properties that are PROPERTY_USAGE_NO_EDITOR
* Extract missing ADD_ARRAY*, ADD_SUBGROUP* macros
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
* Placeholder textures
* Placeholder meshes
* Placeholder material
This PR is the first step towards implementing https://github.com/godotengine/godot-proposals/issues/2756
It adds an asset type that uses no resources, which can be used to replace the existing ones on export for using on the upcoming server export.
